Grok, the AI model developed under Elon Musk's xAI initiative, has introduced a new Smart Auto Mode that dynamically selects the appropriate level of processing power based on the complexity of user queries. This feature allows Grok to deliver quick answers for simpler questions and engage in deeper reasoning for more complex ones. Users retain the option to manually override the automatic setting and force the model to apply heavy thinking with a single tap. The Smart Auto Mode is currently available on the web version of Grok, with plans to roll it out soon on iOS and other app platforms. The update aims to enhance user experience by optimizing response times and computational resources.
